Description
- E220-900T30S is a new generation of LoRa wireless serial port module (UART), based on Semtech's original LLCC68 chip design. It has a variety of transmission methods, works in the (850.125?930.125MHz) frequency band (default 873.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
- New generation LoRa. Compared with the traditional SX1276 solution, the transmission distance is longer, the speed is faster, and the power consumption is lower; it supports functions such as air wake-up, carrier monitoring, and communication key, and supports sub-packet length setting. Ebyte can provide customized development services. Compared with the LLCC68 scheme, this scheme has a high cost performance advantage. The product can cover an ultra-wide frequency range of 850?930MHz

Features
Using LLCC68 chip solution, it has significant advantages of low power consumption, fast speed and long distance;
Under ideal conditions, the communication distance can reach 10km;
The maximum transmit power is 30dBm, and the software is multi-level adjustable;
Support users to set the communication key by themselves, and it cannot be read, which greatly improves the
confidentiality of user data;
Support RSSI signal strength indicator function for evaluating signal quality, improving communication network,
and ranging;
Support air wakeup, that is, ultra-low power consumption function, suitable for battery-powered applications;
Support fixed-point transmission, broadcast transmission, channel monitoring;
Support the global ISM 868/915MHz frequency band;
The parameters are saved after power off, and the module will work according to the set parameters after power on
again;
Efficient watchdog design. Once an exception occurs, the module will automatically restart and continue
to work
according to the previous parameter settings;
Support the data transmission rate of 2.4k?62.5kbps;
Support 2.3~5.5V power supply, power supply greater than 5V can guarantee the best performance;
Industrial standard design, supporting long-term use at -40?+85?;
Dual antennas are optional (IPEX/stamp hole), which is convenient for users to develop and integrate.
